Thank you very much for the information. The problem is solved. First off, I apologize for not telling that it was Firefox, I was having the problem with. But, honestly, I thought that Konqueror was doing it too because there are occasions when Konqueror wasn't giving up thumbnails and file content (but I know now that that's something else that I'll bring up in another thread). I prefer Ffx as a web browser and Konqueror as a file manager, and how it looks.
Thanks, AndrzejL, for the hunch. I went to "Re: (SOLVED) FireFox needs to slow down" and changed network.http pipepining.maxrequests from 10 to 6 (6 because that's what worked for Ramchu).
Thanks, T6, for " . . . there is a option you can activate to make the browser not show images in firefox." I went to edit>preferences>content and reselected "load images automatically." I must have deselected it at some point because I was getting images all along before. That bit of information is a big help. In case anyone is wondering why I deselected it, let me just say that I have no clue. I don't even remember doing it.
Anyway, thank you all very much.
